[Zope] Using a template for all pages, or calling dtml as a function, or perhaps switch to Zpt ??

[a.p.bourne@salford.ac.uk]

Max,

Is your index_html object a DTML Method or a DTML Document?

If it's a DTML Document then acquisition won't work in the way you 
expected.  

Change it into a DTML Method and the structure you describe below 
will work.

You will not need to create an index_html object in every sub-folder 
(but each subfolder can optionally have its own unique 
primary_content and secondary_content objects).

Regards,

Andy Bourne
